Blinky flashing but no result on board

sjcalds

I am trying to flash blinky to NRF5340DK but after a "successful" flash, there is no blinking of the LED. I have tried two boards and multiple blinky examples. There is a problem shown below that dissapears when I click blinky_pwm under the build.

I have found posts with similar issues, but they were resoved by switching the runner to nrfutil, which I already have.

The only other spot with warnings is shown below which happens during the build.

I am running SDK v3.4.0.

Thank you for your help!

    Hi, can you try this build command:

    Building blinky_pwm
    west build --build-dir c:/MJ/NCSv3.4.0/blinky_pwm/build c:/MJ/NCSv3.4.0/blinky_pwm --pristine --board nrf5340dk/nrf5340/cpuapp -- -DDEBUG_THREAD_INFO=On -DCONFIG_DEBUG_THREAD_INFO=y -Dblinky_pwm_DEBUG_THREAD_INFO=On

    This works for me and LED1 is blinking on the nRF5340 DK.
